<p>自定义媒体每层参数</p>
<ul>
<li>1、格式 高基数 第一层高倍数 第一层码率 第二层高倍数 第二层码率 第三层高倍数 第三层码率 第四层高倍数 第四层码率 <br  />
 说明 <br  />
 1）默认宽高比16:9 <br  />
 2）编码宽高最后被裁成16整除 <br  />
 3）码率计算可大致参考文件 《码流甜点区域》<br  />
 例如 "120 3 750 4 950 6 1200 9 1600" <br  />
 第一层 分辨率 宽640（120*3/9*16）高 360（120*3）； 码率750kbps <br  />
 第二层 分辨率 宽848（120*4/9*16）高 480（120*4）； 码率950kbps <br  />
 第三层 分辨率 宽1280（120*6/9*16）高 720（120*6）； 码率1200kbps <br  />
 第四层 分辨率 宽1920（120*9/9*16）高 1080（120*9）； 码率1600kbps <br  />
</li>
<li>2、作用 <br  />
 自定义分层参数和码率</li>
<li>3、其他说明 <br  />
 二层或多层配置参数一致 <br  />
 1）无意义，会增编码损耗。 <br  />
 2）不会节约码率，码率取决于设置订阅层的码率；想减少流量，降低分层分配的码率 <br  />
 如 "120 3 750 3 750 6 1200 9 1600" 第一层和第二层一样 <br  />
 当第一层和第二层都被订阅，实际第一层和第二层都在编码，没必要；可改成 "120 3 750 6 1200 9 1600"，都订阅一层 <br  />
 以上情况设置成 "120 3 750 6 1200 9 1600" 会比 "120 3 750 3 750 6 1200 9 1600" ，节约上行码率和减少编码损毁。 </li>
